Shanghai built dairy embryo Center

Introduction: can cattle produce cows? Recently, the cow embryo bioengineering center established by Shanghai Zhenyuan dairy and Shanghai Bioengineering Research Institute has given a positive answer The center makes full use of the huge number of cattle resources in China, and tests the transfer of high-yield cow embryos to high-quality cattle to "borrow the abdomen to have children" It is expected that by the middle of March next year, the first batch of "cattle and cows" will be born According to the introduction, the industrialization of cow embryo biotechnology is a new revolution of Cow Reproduction Technology after artificial insemination technology It can not only give full play to the reproductive potential and excellent genes of pure and high-quality cows, strengthen the breeding speed of cows, but also increase the annual milk production of each recipient cow by 34 tons, and save a lot of forage and feed resources Greatly improve the economic benefits of dairy production It is reported that the center has carried out superovulation treatment on 4 batches of 23 cows and obtained 146 high-quality embryos It is planned that the annual output of cow embryos will reach 5000, ranking at the national leading level The conception rates of fresh embryo and frozen embryo transferred by cows are 17% and 5% higher than the domestic average respectively In the early October of this year, the first batch of six Holstein calves of all compatriots (the same parents) will be born successively, which is the first time in the field of cow embryo transfer in China At present, dairy farms and professional dairy households in Zhejiang, Heilongjiang and other places have ordered 4000 high-quality cow embryos from the center
